HEEL-SEAT-FITTING MACHINE.

Application filed October 25, 1824. Serial No. 745,892.

This invention relates to the manufacture of shoes and is illustrated herein as embodied. ir heel-seat tilting machine adapted. to trim the heel-seats of soles of shoes for the reception of heels.

In the manutacture of shoesto which wood and some other types of heels are to be attached, the heel-seat portions of the soles of the shoes are prepared for the attachment ot the heels by what is known as the heel-seat fitting operation. Heels of the types referred to are formed with concave attaching surfaces, and. it the purpose of the heel-seat fitting operation to trim the heel-Seat portion 011? the'sole so that the periphery of the concave attaching surface of the heel will contact closely with the adjacent shoe upper, the margin of the heel-seat portion of the sole being thus completely covered by the attached heel and concealed from view in the completed shoe. Moreover, the shape to which the heel-seat oil' the sole of a shoe is trimmed by the heel-seat fitting operation should be complcmental to the shape of the attaching surface of the heel to be attached so as to provide a good bearing for the heel upon the sole.

The stock trimmed from the heel-seatportion of the sole of a shoe during the heel-seat fitting operation .is roughly of a horseshoeshaped form, a breast cut or cuts being made transversely of the sole to receivethe breast of the heel. In order that a shoe may have a neat and trim a npearance and that its heel may be securely attached, it is necessary that the trimming of the heel-scat portion of its sole to fit the heel. which is to be attached be done accuratcl y. Thus the position of the breast cut longitudinally of the sole of a shoe and both the width and length to which the heel-scat is trimmed must be varied in accordance with tliefsize and style of the heel to be attached.

l Vhen the heel-seat fitting operation is performed by hand, it is custon'iary for the operator to locate the breast cut by applying to the sole the particular heel which is to be attached and marking on the sole the position occupied by the breast of the heel. This stock trimmed off at the sides of the heelseat depend upon the judgment and skill of the operator, and there is a distinct tendency when performing the operation; by hand to remove too much stock since it is practically impossible to attach the heel it too little stock is removed, and it is very difiicnlt to trim off by hand exactly the right amount.

Heel-seat fitting machines have been proposed in which the position of the breast cut and the forward extent of the trimming cut were determined by the use of the heel which was to be attached to a shoe, or by a heel like that one, as a templet, the machine being provided with relatively movable gage members arranged to contact with the breast and the rear of the heel and operatingto con trol the performance of the operation. It is an object of the present invention to provide a heel-seat fitting machine having improved means for controlling the trimming of the heel-seat portion of the sole of a shoe. To this end the machine herein disclosed is provided with means for measuring both the length and the width of the heel whichis to be attached to the shoe or a. heel like that which is to be attached to the shoe operated on, thereby controlling the position of the breast out, the length of the trimming cut and the width to which the heel-seat portion is trimmed. The illustrated machine, moreover, is arranged so that when certain of. its parts are moved into inoperative position at the conclusion of the operation on each shoe, parts ofthe measuring device are withdrawn from the heel which has controlled the trimming operation sothat, if necessary, the heel may be readily removed and replaced by another. When the machine is again started to operate on the next shoe, the parts of the measuring device which have been with drawn move back into engagement with the heel so as to control the heel-seat fitting operation in accordance with the dimensions of that heel.

With the above and other objects and features in view the invention will now be described in connection with the accompanying drawings, and pointed out in the claims.

In the drawings,

The present invention is disclosed as embodied in a machine of the type disclosed in Letters Patent of the United States. No. 1,661,391, granted March 6, 1928, on my co pcnding application and having Serial No. 738,449, filed September 18', 1024 to which reference should be had for a com plete disclbsure of parts not fully described herein. In the illustrated machine a recessed bedplate 10 is supported upon legs 12 and 14 which are held rigid by spacing spacing bars 16 and upon which there is mounted a cross frame 18 carrying a worksupport-ing post 20 provided. with a last spindle: Curved jaws or crease plates 22 are mounted for movement in th'ebed plate 10 under the control of a hand lever 24 and are adapted to receive and close in upon the rand crease of a shoe supported upon the spindle of post 20.

Mounted for sliding movement upon the upper part of the bed plate 10 is a sliding table 26 comprising two parallel plates which maybe moved" toward and away from the operator under the control of manually operated lever 28. Actuation of the lever 28 operates to bring the sliding table 2'6" Forward, working through a rod 34 to raise the post 20 in order to hold the work firmly in engagement with the crease plates The sliding table supports a rotary milling cutter 35. which is mounted on the rotor shaft or an extension of the rotor shaft of an electric motor 30, as shown at 46 (see Figs. 1 and 3). Shaft 46 passesthrough a sleeve 29 termed rigid with a disk 32 (Fig; 1) slida'ble between the two plates of the table 26; The electrical supply for the motor S0 is doubly controlled by a manual switch 31 and an automatic switch 33 which is so arranged to contact with the sliding table 26 that it will disconnect the motor from its source at sup-ply whenever the table is moved to its rear or inoperative position;

The patlr of movement of the rotary cutter is controlled by an adjustable templet coi'i'ipr si'ng plates 36 and 38 (Fig; 3) pivoted at 40' and 42 to the sliding table 26 and provided with a horseshoeshaped slot 44 for controlling the path o t movement of shaft 46', on which the rotary cutter is mounted. The plates of the adjustable templet are provided with overlapping edges so that the continuity of the slot 44 is not broken in consequence of their adjustment, and the forward ends of the plates are joined by a spring 48 tending to close the templet to bring the spread of slot 44 to its narrowest condition. An enlarged portion or vestibule 50 of the slot 44 is provided for the reception oi? the shaft 45 of the rotary cutter during the time that the cutter is not actually in trimming operation..

The driving motor 30 is supported upon a manually operated lever 59 which inturn is pivoted upon another manually operated lever 54 extending in an angular direction to the first lever; and by means of these levers the operator is able to cause the rotary cutter to pass completely around the horse shoe-shaped slot to etlect the trimming op-- eration by means of which the rear end ot the sole is beveled to form the heel-seat.

In order to complete the trimming operation by making a breast cut, the machine has a breast cutting knife (30 carried by a sliding bar 62 which is mounted for movement transversely of the work and of the machine in hearings in a carriage 64 mounted for forward and rearward adjustment in the bed 10 of the machine. Actuation oi the breast cutting kniie 60 is edected by movement of a trcadle connected to the sliding bar 62 by means of a treadle rod 72 and a bell crank lever 74.. A spring-controlled member 76 upon the treadle rod 72 is connected with the post 20 so that the post is elevated to hold the work in close engagement with the crease plates when the treadle 70 is depressed to actuate the breast cutting knife 60, as disclosed in said Letters Patent No. 1,661,391.

A stop 66 (Fig. 1) carried by carriage 64 and extending across the 'lorward portion oi: the horseshoe-shaped path. of movement; of sleeve 29 limits the forward extent of the path of the rotary cutter in accordance with the position oi the breast cut.

In order to enable the operator to control and adjust the action of the machine so as to fit shoes of various sizes to receive correspondingly sized heels, the illustrated machine is provided with a hand-wheel 80 screw-connected tothe carriage 64 which carries the breast cutting knife 60 and the stop 66 so that by rotating the hand-Wheel carriage 64 may be adjusted from the front to the rear of the machine in order properly to position the breast out and to limit the forward extent of the trimming cut on account of the differences in the styles and shapes of wood heels and the consequent differences in the lengths and widths of the heel-seats of the shoes to which the heels are to be attached, it is found desirable to provide mechanism by means of which the heel-seat portion of a heel may be measured upon the machine and the adjustill) ment of the machine may be directly dependent upon the measurements of the heel itself. To this end, the heel used is the one which is to be applied to the particular shoe or one like that heel, and this heel controls both the length and the width to which the heel-seat is trimmed. The illustrated machine has a length-measuring device comprising a fixed member 82 secured to the side of the bed plate 10 for engaging the rear of the heel and a heel breast gage 84 secured to and movable with the adjustable carriage 64. Heel breast gage 84.- is provided with a bottom plate 85 for supporting an inverted heel as indicated in Figs. 2 and 3, so that after the heel has been positioned on bottom plate 85, rotation of the hand-wheel 80 will move the carriage64 to bring the heel in contact with the gage members 82 and 84, thereby positioning the knife 60 and the stop 66 to make the breast cut and to limit the forward movement of the rotary cutter in accordance with the length of the heel. In order to adjust the pivoted templet plates 36 and 38 in accordance with the width of the heel measured, the machine is provided with a lever 86 pivoted at 88 upon the sliding table 26 and provided with depending pins received within suitably shaped slots 90 which areso arranged thht the rotation of the extended end of the lever 88 toward the front of the machine will be effective to spread apart the templet plates against the tension of the spring 48. The means provided for measuring the width of the heel are interconnected with the adjusting lever 86 so that the lateral control of the adjustable templet is directly dependent upon the width of the heel being measured.

The means for measuring the width of the heel and controlling the lateral adjustment of templet plates 36, 38 comprises a plate 94 carried by a link 92 for engagement with the side of a heel supported on the bottom plate 85 of the heel-measuring device. Link 92 is pivoted to a pair of hell crank levers 96 for parallel movement toward and from the side of the machine. The outer arms of hell crank levers 96 are connected by a link 98. The connections between link 92 and control lever 86 comprise a bell crank lever 100 pivoted upon anarm 102 mounted upon the sliding table 26, one end of this bell crank lever 100 being pivotally connected with the end of the lever 86, while the other end of the bell crank lever 100is provided with a depending roll 101 adapted to be received within the sides of a groove 104 formed ina part of the link 92. A spring 106 tends to move the lever 86 into a position to close the templet plates and at the same time urges the side gage plate 94 in contact with the side of the heel. member 108 (Fig. 1) adjustahly mounted upon a bracket 110 upon the frame of the A stop machine is so located that it will contact with the lever 86 adjacent to its connection with the ball crank 100 when the sliding table 26 is moved to rearmost position to move the lever 86 against the tension of the spring .106, thus moving the templet plates apart and at the same time moving gage member 94 away from the heel last measured. The roll and groove connection between the sliding table and the heel-measuring device will allow forward and rearward movement of the table 26 without disturbing the connection between the templets and the measuring device.

In the operation of the machine, a shoe mounted upon a last is placed on the spindle of post 20 and moved rearwardly to bring its rand crease into engagement with crease plates 22, the crease plates being moved into the rand crease of the shoe by means of lever 24. After the corresponding heel has been placed in the measuring device, hand-wheel 80 is rotated to cause the heel to be engaged by gage members 82, 84. This moves knife bar 62 into position as determined by the length of the heel properly to locate the breast cut and sets the stop 66 for coaction with sleeve 29 of the rotary cutter to limit the movementof the rotary cutter lengthwise of the shoe. The sliding table is then moved forward by means of the hand lever 28, thereby raising the post 20 to press the work firmly into engagement with the crease plates 22 and operating switch 33 to supply current to motor 30. The shaft of the r0- 7 tary cutter at this time should be positioned in the enlarged portion or vestibule of the horseshoe-shaped slot 44: so that the cutter will not contact with the work as the table is being movedinto forward position. As the table is moved forward, the adjustable templet plates 36, 38 are positioned in accordance with the width of the heel in the measuring device, springs 48 and 106 moving plates 36, 38 toward each other until gage member 94 contacts with the side of the heel. When the table has been brought into forward position, the operator grasps the handles of levers 52 and 54 and moves the milling cutter around the horseshoe-shaped slot, thus removing the superfluous material around the periphery of the heel-seat and making a beveled cut so that the heel-seat portion of the sole will correspond in form to the attaching surface of the heel. The trimming operation finished, the operator moves the cutter shaft back into the enlarged portion 50 of the templet slot and actuates lever 28 to slide table 26 back to its rearmost position. This also moves gage member 94 out of engagement with the side of the heel. He then depresses treadle 70 thereby actuating the breast cutting knife to make a transverse cut which will be properly located lengthwise of the shoe for coaction with the breast of theheel. As has been noted, this depression of the pedal likewise is ellectiveto raise the post 20 to hold the work firmly in engagement with the crease plates during the breast-ing oper ation. This part of the operation finished and the treadle '70 released, the work may be released by actuation of the lever 24 and removed from the machine.

It the next shoe to be operated on is to have the same size and style of heel as the last, the heel previously used to control the operation may be left in place on plate 85. Otherwise it is removed and another heel, either the identical heel which is to be attached to the nextshoe, or a heel like that one, is placed on plate 85, and the machine is again operated in the manner just de scribed.
